The <span style="font-family: monospace;">format</span> may be <span style="font-family: monospace;">'RGB'</span> or <span style="font-family: monospace;">'RGBA'</span>. If a <span style="font-family: monospace;">size</span> is specified, it should be a tuple (<span style="font-style: italic;">width</span>, <span style="font-style: italic;">height</span>),
and the array will be implicitly reshaped to match the specified size
and format. Otherwise the array must have 3 dimensions, the size is
inferred from the first two dimensions of the array, and the third
dimension must match the number of bytes required by the format.<br><br>If
possible, the returned Image will share data with the original array,
but this is not guaranteed. The effect of modifying the array after
creating the image is undefined.</dd></dl>---</body></html>
